The 77-year-old billionaire owns millions of dollars worth of real estate in California. His primary home is reported to be the sprawling Jack Warner Estate in Beverly Hills.

The mansion is named for Jack Warner, the cofounder of Warner Bros, who built it in 1937.

The nine-acre property includes a 13,600-square-foot Georgian-style mansion, two guesthouses, a tennis court, swimming pool, nine-hole golf course, terraces and gardens, and a motor court with its own service garage and gas pump.

Geffen owns at least two other homes in Beverly Hills. In the spring of 2019, Geffen picked up a $4.65 million Beverly Hills house next door to one he already owned.

Geffen has quite the real-estate footprint in New York as well. He's the owner of two condos, including a 12,000-square-foot triplex penthouse, in the Park Cinq, a luxury Fifth Avenue building near Central Park in Manhattan.

Geffen is known for cruising the seas and hosting celebrity guests on his 453-foot superyacht, Rising Sun.

Geffen bought the yacht for $590 million from Oracle CEO Larry Ellison in 2010, according to Forbes. His guests have included Barack and Michelle Obama, Oprah Winfrey, Bruce Springsteen, and Tom Hanks.

He also cruised in Mallorca with stars including Chris Rock, Orlando Bloom, and Katy Perry.

In March 2020 amid the coronavirus outbreak, the billionaire faced criticism for a "tone-deaf" Instagram post in which he shared photos of Rising Sun in the Grenadines with the caption, "Sunset last night. Isolated in the Grenadines avoiding the virus. I hope everybody is staying safe."

Geffen reportedly had the yacht refitted over a six-month period.

But Rising Sun isn't the only superyacht Geffen has owned. In 2011, less than a year after buying Rising Sun, Geffen snapped up Pelorus, a 377-foot superyacht that he bought for $300 million from Russian billionaire Roman Abramovich.

Geffen has donated hundreds of millions of dollars to educational institutions, museums, and gay-rights causes.

He established the David Geffen Foundation in 1986, which has focused its efforts on five main areas: populations affected by HIV/AIDS; civil liberties; the arts; issues of concern to the Jewish community; and health care.

After he donated $300 million to the University of California, Los Angeles, the university named its medical school after him.

"It seemed as though, if I didn't do it, it wasn't going to get done — they've been attempting this for years and they couldn't raise the money," Geffen told The New York Times in an interview at the time. "I love art, I love L.A., and I could do it, so I did."

Geffen, who came out as gay at an AIDS charity event in the 1990s, has also donated to AIDS and gay-rights causes.

Ten years later, in 2016, Griffin bought another de Kooning painting and a Pollack painting from Geffen for $500 million total.

Geffen owned one of Hockney's famous pool scene paintings for about 12 years. He sold it to British billionaire Joe Lewis in 1995, who kept it for years before selling it at a Christie's auction for a record-breaking $90.3 million in 2018.
